Short presentation
I am Professor emeritus in plant ecology.
Ecology of mire plants and bryophytes: My research focuses on peatland ecology and covers community structure, competition, niche relations, ecophysiology, reproduction, dispersal and metapopulation dynamics in bryophytes. Sphagnum species (peat mosses), rich fen bryophytes and epiphytes are the main study objects.
Book on peatlands: Rydin H, Jeglum JK. 2013. The biology of peatlands, 2nd ed. OUP.
